Changing the Air Text Demo

The Air Text demo is easy to change.

First, copy the existing project. Right-click on "AirText" and select "Copy Project" from the menu.

A dialog box will display. Enter a new name for your version of the project:

Make your new project the current project by right-clicking on the project name and selecting "Set Main Project". In the Project window, click on the plus to the left of the project name to expand the project node. Now, expand the "src" node, then the "org.sunspotworld.demo" package. Select "AirTextDemo.java" from the files displayed.

The source code for AirTextDemo.java will display in the window to the right. Scroll the window on the right down to lines 50 or so. There you will see a series of calls to disp.SwingThis. Change the string "Hi!" to "Yes!".

Now go through the steps previously outlined to deploy and run the new code. When you deploy, the system automatically saves and compiles your changes.

Unplug the Sun SPOT from the USB cable. Now move it back and forth in the air and see if your changes have made it onto the Sun SPOT and are running.

Congratulations! You have mastered the "Hello, world" application of Sun SPOTs!

Now we would like to show you how the Sun SPOT basestation can be used to connect to the free-range Sun SPOTs.
